A method of computing output delay in a mathematical model of an integrated circuit by sorting cells of original design of an the integrated circuit in a topological order. Patterning the gate electrode layer stack comprises a step of patterning the metal layer and the barrier layer with an etch stop on the surface of the interface layer. The rigid main body is generally centered about a longitudinal axis defined by the flexible lead body when the lead body is unflexed. A user is logged as having viewed the program in response to the user completing playback of the file. Each shift actuator is adapted to cause its respective synchronizer to engage and disengage its respective gear sets to and from their respective shaft and further adapted to provide a hydraulic interlock that prevents an associated shift actuator on the same shaft from hydraulically actuating when the shift actuator is already engaged. The processor may notify the healthcare professional of the second medication order, such as by displaying an indication of the second medication order separately from the queue.
